The downfield shifts of the acidic proton in their 1H NMR spectra are consistent with its expected high acidity. The molecular structures of H(DMSO)2[P(1,2-O2C6H4)3] and H(DMF)2[P(1,2-O2C6H4)3] reveal that the protons in each are O-bound by either DMSO (×2) or DMF (×2...
通过元素分析分析发现,电解产物H/C原子比有了显著提高,体现出该电解体系较高的加氢效率。红外光谱显示,电解过程中C=O键和芳环结构得到了有效还原。煤分子结构中的桥键,如C-O-C,也发生了裂解反应。通过1H-NMR分析,进一步印证了煤电解过程中的结构变化,并提出了可能的反应机理。关键词:...
